Question
The black colour on the beak of finches dominates over the yellow colour. There are 210 individuals with the genotype DD, 245 individuals with the genotype Dd and 45 individuals with the genotype dd. Deduce the frequency of individuals with dominant, heterozygous, and recessive traits.
Solution
The frequency of individuals with the dominant genotype: 𝑝² = 0.49
The frequency of individuals with the heterozygous genotype: 2𝑝𝑞 = 0.42
The frequency of individuals with the recessive genotype: 𝑞² = 0.09
